  • Patent number: 7993529
    Abstract: A treatment method of organic compounds included in waste water, comprising the steps of: supplying waste water to an adsorber 2 filled with an adsorbent 3 therein for adsorbing the organic compounds in the waste water by the adsorbent 3 in the adsorber 2, supplying a current between an anode 9 and a cathode 8 in water including an electrolyte in an electrolyzer 6 for electrolyzing the water including an electrolyte, and supplying an electrolyte resulting from electrolysis in the electrolyzer 6 to the adsorbent 3 in the adsorber 2 for contacting the electrolyte with the adsorbent 3, so that the organic compounds adsorbed by the adsorbent 3 are desorbed or decomposed.
    Type: Grant
    Filed: March 25, 2010
    Date of Patent: August 9, 2011
    Assignees: Hitachi, Ltd., Hitachi Kyowa Engineering Co., Ltd.
    Inventors: Akio Honji, Hayahito Ishii, Akira Mochizuki, Norihide Saho, Tsutomu Tsuyama, Hisashi Isogami
